In the Apollo 11 command module below, astronauts Neil A.
Armstrong, Michael
Collins, and Edwin E. Aldrin
Jr. traveled to the Moon and back on July 16-24, 1969. During that
mission, humans first walked on the Moon, and Columbia carried
the first samples of lunar rocks and soil back to Earth. The heat shield and
exterior of the spacecraft are scarred from the 2,760°C
(5,000&degF) heat generated by entering the Earth's atmosphere at 40,000
kilometers (25,000 miles) per hour.
